Handy little things
Last year we needed to plonk an NTP server somewhere until we got out new time infrastructure in. Somewhat jokingly boss of boss suggested an RasPi. I thought about it and realised that it wasn't such a silly idea. So we purchased two (always have a backup!), threw on CentOS 7 (so they fit in with everything else) and aside from a USB dongle on one of them playing silly they worked fine for several months.
Once they were decommed from that use I took one home, threw on RiPTC and now use it as a VMware Horizon thin client to connect to work.
